Demo Image Variations

In this tutorial, you’ll learn how to generate multiple variations of an existing image using the OpenAI DALL·E API. By the end, you’ll be able to:

• Load and preview a source image
• Call the DALL·E variations endpoint
• Render the generated images

Prerequisites

• Python 3.6+
• Install the OpenAI Python library:

pip install openai

• Set your API key as an environment variable:

export OPENAI_API_KEY="your_api_key_here"

1. Import Modules and Configure the API Key

Begin by importing the necessary modules and loading your API key:

import openai
import os
from IPython.display import Image, display

openai.api_key = os.getenv("OPENAI_API_KEY")

2. Load and Display the Source Image

Use IPython’s display utilities to preview the original asset:

display(Image(filename='./images/lion-cub.png'))

This shows a lion and its cub.

3. Generate Three Variations

Call the DALL·E variation endpoint, specifying the image file, output size, and number of results:

response = openai.Image.create_variation(
    image=open('./images/lion-cub.png', 'rb'),
    size='512x512',
    n=3
)

4. Render the Generated Variations

Display each variation using the URLs returned in the response:

# Variation 1
display(Image(url=response['data'][0]['url']))

# Variation 2
display(Image(url=response['data'][1]['url']))

# Variation 3
display(Image(url=response['data'][2]['url']))

Each variation offers a unique composition or style. Experiment with different source images or parameters to explore new creative directions.
